Make those large LED Video Light Panels more portable by running them off of batteries. Here's a random little video showing you how to power up those CN-600 / CN-900 LED Video Lights using the 14V Sony BP-U30/U60 batteries. It's not the cheapest solution, but compared to other batteries available, it's not too shabby.

This was the same battery adapter that I showed earlier which acts to power up your BlackMagic Cinema Camera. You can find the products below.

Check out this adapter...If you've already got a v-mount base, this seems to be a great ticket so you don't have to purchase other adapters separate from what is already mounted on your light or shoulder rig:

I think I'm going to go for the 900 light, and I realized I use these large Series7 EX-L96 batteries on my Sony EX1 cameras. These are 6600mAh, so it might be a good run time, though mounting will be a little hard.

I've ordered one of those dual NPF to V-mount adapters from Amazon and a couple of Maximal Power batteries that are rated at 7200 mAh I believe. I'll let you know how long they last on the CN-600 when I get them next week. I read reviews that the Maximal Power are pretty good, if somewhat flimsy on the construction. A friend of mine has a chinese V-mount battery so I'll test the adapter/dual NPF combo against it.

One problem I have with NP-F batteries is that they take waaaay too long to get fully charged. Sometimes close to a full day of charging. What's your experience on them?
Are BP-U60 batteries faster on the charging time? Maybe I have bad chargers? I have 3 Maximal Power branded batteries and one supposedly original Sony battery which now dies for no reason at any moment and resurrects after a 1 second load in the charger. Quite odd.

The BP-U options may be more expensive, but if they charge faster I may as well consider them.

On paper (since I haven't tested the NPF to V-mount adapter yet) the NPF solution is cheaper because the NPF batteries are less than half the cost of the BP-U30/BP-U60 for about the same capacity. The adapters are about the same for both battery types around $50-60 and in the case of the BP-U30/BP-U60, I'll have to add the cost of a couple of charges, whereas I have a few chargers for the NPFs already. The only drawback in the NPF solution is that you'll have to buy the NPFs in pairs since they are 7.2 V.

Cheesycam strikes again! The caped crusader for cheaper video solutions! Not bad, not bad at all! I have to do the math to see how it compares to my solution (which I haven't tested yet, as I have not received the adapter yet). I bought this adapter

Now, these are rated at 7200 mah each, which if I've done the math correctly should give you a bit more runtime than a 190wh V-mount battery for about 1/3 of the cost. Now I have to crunch the numbers for your solution. Oh, and my CN-600s are the newer generation with the more rounded body, and they do not have those 1/4-20 holes in the back, damn it!
